What are the key technical challenges and design options for optimizing a geothermal heat pump design? Review the pros and cons involved with centralized or distributed pumping, with hybrid or decoupled systems, and with the controls that can guide them.
With the help of advances in intelligent controls and a shift in design mindset, these systems can steer buildings toward smaller equipment sizes and associated savings. Review three projects and consider the benefits of keeping an upcoming project in the loop.
“M” is for “More than one way to get the job done.” In this
two-school tour, we start with an underfloor ventilation design and
geothermal energy center in action. Then we take notes at a school
with displacement ventilation, radiant floor heating, and radiant
ceiling cooling. Round out the lesson with discussion of ASHRAE
62.1-2007 guidelines and the Wells-Riley equation for infection and
ventilation, and your next school project is practically getting
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
